  DWORD dwExpectedFileSize, 
  LPCTSTR lpszFileExtension,
  LPSTR lpszFileName, 
  DWORD dwReserved
);

Parameters

  • lpszUrlName
    [in] Address of a string variable that contains the source name of the cache entry. The name string must be unique and should not contain any escape characters.
  • dwExpectedFileSize
    [in] Unsigned long integer value that contains the expected size of the file needed to store the data corresponding to the source entity. If the expected size is unknown, set this value to zero.
  • lpszFileExtension
    [in] Address of a buffer that contains information maintained in the cache database for future use.
  • lpszFileName
    [out] Address of a buffer that receives the file name. The buffer should be large enough (MAX_PATH) to store the path of the created file.
